Abstract

A magnetic transducer head assembly comprises a pair of magnetic core halves of generally C-shaped configuration and a coil wound on one of the core halves. The limbs of the C of each core half is in abutment relationship with those of the other core half to define a medium-contacting face and a magnetic gap on the medium-contacting face. The magnetic gap includes an inner gap section and outer gap sections respectively disposed on opposite ends of the inner gap section. Each of the outer gap sections has a gap length much greater than the gap length of the inner gap section and is in the shape of a meandering configuration which is formed by a series of crests on one of the core halves and a series of troughs on the other core half. The tips of the crests of each core half lie on an imaginary plane which is aligned or retracted from a plane defined by the inner gap section.
